Monday's early-morning storms produced flooding, knocked down trees and spawned at least two tornadoes.

The National Weather Service in Jackson said a survey of damage in Marion County confirmed an EF1 tornado formed at 8:19 a.m., southwest of Columbia. It had maximum winds of 100 mph, a width of 100 yards and a path length of three miles, authorities said.

The tornado was reported about 8 a.m. in the southern part of the county, near the Mississippi-Louisiana state line, authorities said.

A team of meteorologists were set to survey damage Tuesday in Franklin County around the Meadville area, the weather service said.

Residents in the Presidential Hills neighborhood in Jackson blamed clogged storm drains for flooding there. James Garfield Circle was flooded with water that went nearly up to the doors of at least two homes.

Jackson officials said city workers have cleaned the drains several times, but said the problem is caused by illegal dumping.

Monday's storms also knocked trees down on roads and power lines in areas around central Mississippi.

Emergency officials said a tree fell on a trailer along Gloster Road, south of Meadville. No injuries were immediately reported.
